Services declared as oneshot are expected to take some action and exit immediatelly (thus, they are not really services, no running processes remain). A common pattern for these type of service is to be defined by a setup and a teardown action.

Let's create a example foo service that when started creates a file, and when stopped it deletes it.

Define setup/teardown actions

Create executable file /opt/foo/setup-foo.sh:

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)



	(** [dir_is_empty dir] is true, if [dir] contains no files except
	* "." and ".."
	*)
	let dir_is_empty dir =
	Array.length (Sys.readdir dir) = 0

	(** [dir_contents] returns the paths of all regular files that are
	* contained in [dir]. Each file is a path starting with [dir].
